Definitions

  • the present invention has as an object an apparatus for rapid elastic attachment of a railroad rail on cross-ties, of cement, wood, plastic material, of the type comprising a rod whose spring head in the form of an open ring rests on the shoe of the rail, furthermore centered on its support by a shim or tie plate, while its other end comprises a hooking means associated with the cross-tie making it possible to tension the spring head on the shoe of the rail after the rod has been moved a half-turn.
  • an object of the present invention is to provide a device having two associated means for progressively tensioning the spring head of the attachment rod of the rail.
  • the first means consists in the difference of level which results from the slope which affects the upper surface of the shim, or the centering tie plate of the rail and which extends the slope from its shoe such that by maneuvering the attachment rod by a half-turn, one brings its head from a low position to a higher position, exerting a high tension on the flange of the said rail.
  • the second means consists of a cam formed by the internal shoulder reserved in an insulating anchoring sheath of the "PLASTIRAIL" type inserted in the cross-tie and to which is hooked the free end of the attachment rod of the rail after it has been turned by a half-turn, the shoulder resulting from two successive bores hollowed out of the sheath.
  • the second tensioning means of the spring rod consists of a steel container included in a facing provided in the cement or wood cross-tie, at right angles with a bore hollowed out of the said cross-tie, to which corresponds an opening provided in the centering tie plate of the rail on the shoe of which is supported the head of the spring rod placed in tension, after it has been turned by a half-turn, by hooking of its projecting heel to an internal edge which the bottom of the container bored with an orifice corresponding to the cross-section of the spring rod reserves.
  • the second tensioning means of the spring rod consists of a shoulder resulting from the difference in diameters of two bores hollowed in the centering tie-plate of the rail fixed by sleeper-screws if it rest on a wood cross-tie, or by insulating anchoring sheaths of the type known under the mark "PLASTIRAIL” if it rests on a cement cross-tie, the shoulder allowing for the hooking of the eccentric heel of the spring head after it has been turned by a half-turn, a shim immobilizing the said spring rod in the tightening position on the shoe of the rail.
  • the tensioning means of the spring head are hollowed out of a depression which serves as an anti-return abutment in which is engaged the heel of the spring rod.
  • the centering shim of the rail comprises an opening adapted to the sections of the spring rod and its heel and offset with respect to the bore of the anchoring sheath for blocking it in part when the spring rod is introduced therein, while one of its surfaces, resting against the lateral wall of the housing reserved in the cross-tie, is opened out to assure a slight pinching resulting from the lateral forces exerted by the spring rod, when it is tensioned, against a small flange capping the shim.
  • FIG. 1 is a longitudinal cross-sectional view of the attachment apparatus of a rail on a cement cross-tie.
  • FIG. 2 is a transverse cross-sectional view at the level II--II of FIG. 1.
  • FIG. 3 is a detailed elevational view of the spring rod head of the apparatus.
  • FIG. 4 is a longitudinal cross-section view of the attachment apparatus of a rail on a cement or wood cross-tie, equipped with a centering tie plate of the rail.
  • FIG. 5 is a transverse cross-sectional view at the level III--III of FIG. 4.
  • FIG. 6 is a second view in transverse cross-section at the level IV--IV of FIG. 4.
  • FIG. 7 is a longitudinal cross-sectional view of the attachment apparatus of a rail on a cement or wood cross-tie, equipped with a tie plate attached by traditional means.
  • FIG. 8 is a transverse cross-sectional view at the level V--V of FIG. 7.
  • FIG. 9 shows a diagram illustrating the principal of operation of the apparatus which is the objection of the invention.
  • reference 1 designates the shoe of a railroad rail resting on a cross-tie of cement, or wood 2 by means of an elastic sole 3, or resting on a metallic or reinforced plastic material tie plate 4 in the known manner.
  • FIGS. 1-3 illustrate a first embodiment of the attachment apparatus of the rail being discussed.
  • This sheath comprises a first bore 6 of oblong cross-section as is seen in FIG. 2, preceding a second bore 7 of circular cross-section. From the difference in cross-section of these two bores results a shoulder 8 which can have a descending slope directed towards the interior, i.e., towards the median portion of the cross-beam 2, to serve the role of a cam. As FIG. 2 illustrates, a portion of the oblong cross-section of the bore 6 is hammered out to form two abutments which exist over the entire height of the bore.
  • the attachment apparatus of the rail consists, according to the invention, of a spring rod 9 made out of steel wire, or reinforced plastic. At its lower end, this rod comprises an eccentric heel 10 having a rounded end forming a hook 11 adapted to cooperate with shoulder 8 of insulating sheath 5. The cross-section of the hooked portion 11 of the heel is slightly lower than the rod itself to allow for its passage in the bore 6 of the anchoring sheath 5.
  • the rod 9 forms, at its other end, an open ring 12 extending laterally at an acute angle as is illustrated in FIGS. 1 and 3. This ring 12 constitutes the spring head of rod 9 and can comprise a flat support portion 13 on the shoe 1 of the rail.
  • the apparatus is completed by a centering and maintenance shim 14 of rail 1. It is an element of metal or plastic material having a rectangular shape whose upper surface 15 has a slight slope extending that of the shoe of rail 1.
  • This shim 14 is bored by an orifice of oblong cross-section 16 capped by a small support flange 17 of spring head 9.
  • shim 14 When shim 14 is in the position of FIG. 1, its orifice 16 is offset with respect to the bore 6 of sheath 5, which causes its partial blocking.
  • One of the two lateral sides of shim 14 widens out upwardly, particularly the side 18 in contact with wall 20 of the opening extending through cross-beam 2.
  • the other side 19 abuts against the lateral slice of the shoe of rail 1.
  • the anchoring sheath 5 is correctly positioned during molding of the cement cross-beam 2, the shoulder 8 forming a cam directed towards the shoe of rail 1, as seen in FIG. 1.
  • the centering shim 14 and spring rod 9 on which it is first engaged, constitute thus a movable assembly in two elements.
  • the spring rod 9 of this assembly is introduced by its heel 10, in a manual or automatic fashion, in the bore 6 of the anchoring sheath 5 along the position shown in dashed lines in FIG. 1, the head 12 being positioned on the centering shim 14 which has been mechanically adjusted in its seat of cross-tie 2.
  • FIG. 1 the free end, shown in dashed lines, of ring 12 constituting the tightening head of shoe 1 of the rail, can extend on the centering shim 14 to stop it from escaping outside of its seat under the action of the lateral force which is exerted by spring 9 against semi-collar 17 of shim 14.
  • rail 1 rests on the centering tie plate 4 by means of the elastic sole 3.
  • this tie plate 4 is included in a seat 22 of the cement or wood cross-tie 2.
  • the ends of tie plate 4 are bored with a first orifice 23 of oblong cross-section surrounded by a small flange 24, opening into a second orifice 25 having a sectorial shape as is shown by FIG. 6 to allow for the introduction of the spring rod 9.
  • a steel container 27 having a wall widening out downwardly whose bottom, bored with an orifice 28 of cross-section corresponding to a bore 29 of cross-tie extending vertically the orifice 25 of tie plate 4, reserves an edge 30 hollowed out of a depression 31 which cooperates with surface 11 of heel 10 of spring rod 9.
  • rail 1 rests also on a tie plate 4, furthermore affixed to the wood or cement cross-tie 2 by means of sleeper-screws, or insulating anchoring sheaths known under the mark "PLASTIRAIL".
  • This tie plate 4 made out of metal or plastic material, comprises, at its projecting ends 32, the tensioning means of spring 9. To this end, portion 32 is bored with a first orifice 33 of oblong cross-section allowing for the introduction of rod 9 and preceding a second orifice 34 of circular cross-section. The difference in diameters of the orifices 33 and 34 results in a shoulder which can have a descending slope 35 directed towards shoe 1 of the rail. This shoulder comprises a depression whose edges 36 serve as anti-return abutments of heel 10 of the spring rod.
  • a shim 37 can be introduced into orifice 33 of tie plate 4 to immobilize the spring rod 9. However, the shim is not necessary if a portion of the bore 33 is hammered out as shown in FIG. 8, to form two abutments which continue over the entire height of the bore and prevent a flexion of the spring rod 9.
  • line XX' shows the pivot axis of the attachment rod 9
  • line YY' shows the displacement axis of the spring head 12 of rod 9.
  • the spring head 12 When the rod 9 is introduced into the anchoring sheath 5, or directly in the bore of cross-tie 2, or further in the tie plate 4, the spring head 12 is in the position RN1 and the heel 10 in the position B1.
